The list is a broad mix of cities big and small, ranging from Columbus, Ohio, and Indianapolis to Los Angeles and New York. It includes many of the early favorites, including Austin, Denver, Boston, Toronto and Washington, D.C. Three of the 20 finalists are near the nation’s capital, where Amazon has 2,500 employees.

Chicago was seen as a likely contender, based on Amazon’s criteria of wanting to be in an urban area with more than 1 million people within 45 minutes of an international airport and preferably have direct access to mass transit.

Amazon first announced its search for a second headquarters in September 2016, prompting a rush of bids from cities around North America to host the company.
